When talking about Wilmer Valderrama she said: "We have been together for almost five years now, off and on.

"The only times that we were off was when I was not in a healthy state of mind, or he was like: 'I can’t be with you until you get sober.' So I did, and then that made our relationship so much stronger."

The couple are on the road to marriage, but Demi’s sexuality is still questioned.

When asked about her new song Cool For The Summer and whether it was about Ruby Rose she said: "I don’t feel like any of my past or future—when it comes to relationships that may have happened or not have happened—are of any concern to anybody. What matters to me is my relationship with Wilmer.

"Humans are humans, and when you connect with somebody on a spiritual level it doesn’t matter."
